Have tried to play it without cheats and found it impossible to do. It is not my computer or garphics card either, I have the following.

1. Intel(R) Core(TM) i5 CPU
2. NVIDIA GeForce GTX 460
3. 2048 MB per Dual channels
4. 1 TB SATA hard drive
5. OS: Microsoft XP SP3

Sadly, for me this game is worthless. It is a waste of my money. Another game for the trash heap.
